GEORGE WHITE, OF ROCK ISLAND, ILLINOIS.

SEAT-BACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 496,467, dated May 2, 1893.

Application filed November 10. 1892. Serial No. 451,548. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE WHITE, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and usefullmprovements in Seat-Backs for Vehicles; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being had to the annexed drawings,

making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in spring backs for carriages and wagons, and it has for its objects among others to provide a simple and cheap yet efficient construction whereby the desired result is obtained.

The objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and inwhich- Figure l is a perspective view of one form of my invention. Fig. 2 is a like view of another form.

Like letters of reference indicate like parts throughout the several views in which they appear.

Referring now to the details of the drawings by letter, on reference first to Fig. l, A designates the seat body and B the wooden or metal back bar to the ends of which are secured the curved arms 0, the ends of which project beyond the ends of the said bar and 'upon which are sleeved the ends of the rail arms D which are held thereon by suitable means as nuts E; the other ends of the rail arms are secured to the sides of the seat in any well known way. The ends of the arms 0 should be provided with shoulders to limit the inward movement of the ends of the rail arms. F are metal braces secured to the vertical portion a of the seat body and to their upper ends are hinged the lower ends of the per ends to the cross bar B of the seat. The back of the seat is designed to be upholstered and the upholstering will of course cover all integral with or rigidly secured to the metal frame H which is designed to be secured in position in any well known way and is provided with the horizontal extensions or arms I) and c to receive the bows and supports of the top, not shown- I are spring arms secured at their upper ends to the cross bar B and at their lower ends to the rear cross rail H of the said frameH as clearly seen in said Fig. 2.

In all of the forms shown the back possessses the necessary yielding ability to permit it to oscillate under pressure. The rail arms are practically spring arms and the whole back bar is resiliently mounted or supported. The result is a very easy seat back and one which takes up or counteracts all jar occasioned by the jerking movements of the horse or by running over uneven surfaces.

What I claim as new is- The combination with the back bar of a seat, pivotally connected with some fixed part, and the frame having the lateral extensions to receive the bows and supports of the top of the curved arms on the ends of the back bar and spring arm rails integral with the said frame and connected with the ends of said curved arms, as set forth.

spring arms G which are secured at their up- In testimony that I claim the aboveI have 1 hereunto subscribed my name in the presence of two witnesses.
